Unless you have the cash to burn don't buy the top end of the price range. You won't notice any difference.
My cables cost around the £10 - £15 mark, Not the cheapest, but good solid cables. I was given a cable that cost £120 by someone who was emigrating. Anyway, I replaced my humble leads with the new one and......absolutely no difference.
I actually saw an ad for a 3D ready HDMI cable the other day. As far as I know the cable has nothing to do with the 3D effect. I suppose there will always be those out there ready to rip off the uninformed!!
